Question 28General Subjects - 1st Asst/Chief

The correct answer is A) the circuit breaker. If a bilge pump is able to develop vacuum but cannot sufficiently pump out the bilges, the issue is likely not related to the circuit breaker. The circuit breaker is responsible for protecting the electrical circuit, and its functionality would not directly impact the pump's ability to pump out the bilges. Instead, you would check for issues such as leaks in the suction piping, the suction strainer being clogged, or the relief valve not being properly seated, as these factors can directly affect the pump's performance.
